Rain Drop Sensor Module

Description

• The comparator output, the signal is clean, waveform, driving ability over 15mA
• Distribution bit to adjust the sensitivity
• Operating voltage 3.3V-5V
• The output in the form: digital switching outputs (0 and 1) and analog AO voltage output
• A fixed bolt hole for easy installation
• Voltage: 5V
• Power indicator, the output signal LED indicator
• TTL-level output, TTL output valid signal is low. Driving capability 100MA so, can directly drive relays, buzzer, a small fan, and so on.
• Sensitivity can be adjusted via potentiometer
• LED lights up when there is no rain output is high, raindrop up, the output ground level, LED light
• Raindrops and control panels are separate, easy to wire leads
• A large area of rain board, more conducive to detect rain
• Board with positioning holes to facilitate installation
• Wide voltage LM393 comparator
